" I love you." Why it worked right then, why the webbing of my godmother's spell frayed as though the words had been an open flame, I don't know. I haven't found any explanation for it. There aren't any magical words, really. The words just hold the magic. They give it a shape and a form, they make it useful, describe the images within. I'll say this, though: Some words have a power that has nothing to do with supernatural forces. They resound in the heart and mind, they live long after the sounds of them have died away, they echo in the heart and the soul. They have power, and that power is very real. Those three words are good ones. "
